PHILIP KRAMER, OF NEW YORK, N. Y..

DUMPING TRUCK OR CAR.

SPECIFICATION forming part of Letters Patent No. 609,816, dated August30, 1898.

Application filed April 11, 1898. fierial No. 677,133. (No model!) Toall whom it may concern.-

Be it known that I, PHILIP KRAMER; a

resident of New York, borough of Brooklyn,

Kings county, and State of New York, have in= vented a new and ImprovedDumping Truck or Car, of which the following is a specification.

My invention relates to dumping trucks, cars, or carts, and has for itsobject to produce a structure of the class described from which itscontents can be dumped either to one side or the other of the car ortruck body in a very efficient manner.

To these ends my invention consists in the construction of a dumpingtruck or car as hereinafter claimed.

My invention will be understood by referring to the accompanyingdrawings,in'which Figure l is a side view of a truck-body and dumpingarrangement embodying my invention. 'Fig. 2 is a section on line 2 2 ofFig. 1; and Fig. 3 is a sectional underneath or bottom plan view of thechute portion of the body, the section being taken on line 3 3 of Fig.2.

In the drawings, A is a body, hereinafter for convenience called atruck-body, although by such term Imean also to include all sorts ofbodies for transporting material, such as car-bodies, cart-bodies, andwagon bodies. The sloping bottoms 0. thereof convey the contents of thetruck-body to the middle portion of the said body. At the middle portionof the said body is an aperture 1), located above a doubledelivery-chute B 0, comprising the sides f f and the inclined bottoms cd, which converge at the apex e. These chutes thus constructedconstitute the delivery-chutes for the contents of the truck, by whichmeans the said contents can be dumped to one side or to the other of thetruck-body. The chute B is provided with a gate g, sliding in a way h,

formed by an inclined bottom a of the truckbody and a cleat g Thissliding gate 9 preferably forms a prolongation of the chutebottom 01,and being substantially parallel with the truck-body bottom a the coalor other contents will have a clear run from the point as to the point yat the end of the de livery-chute O, as will be explained. The slidinggate 9 may be positively operated by any means desired. The meanspreferably employed by me consists of a link j, pivoted at one end 7.:to the sliding gate and at the other end I to a lever m, carried upon arockshaft 71., which is actuated by ahandle 0. The link and leverconstitute a toggle-joint;

' It will be obvious that by drawing the handle downward in thedirection of the arrow in Fig. 2 the toggle-joint system mj will slidethe gate g upward in its ways. The truck body is or may be likewiseprovided with another sliding gate 19, shown as forming a prolongationof the bottom 0 of the delivery-chute B and sliding in a way formed bythe bottom a of the truck-body and a cleat q, parallel thereto. Thissliding gate 19 may likewise be positively operated in any usual manner,but is preferably operated by the link 7", pivoted at one end to thegate 19 and at the other end to a lever 8, carried upon a rock-shaft t,provided with an operating-handle a, which lever and link constitute atoggle-joint.

The operation of my device will be obvious from the drawings. Let it besupposed that the parts are in the position shown and it is desired todump coal contained in the truck body to the left of the saidtruck-body. In that case the handle 0 will be swung downward, therebysliding the gate 9 upward and permitting the coal to have a clear runalong the bottom a, the gate 1:1, and the bottom 0 from the point r tothe point 10. When it is desired to stop the discharge of coal from thechute, all that it is necessary to do is to swing the handle 0 upward,whereupon by means of the toggle mechanism the gate Q will be slidforward and stop the flow of coal, the thinned or sharpened front edge gassisting in the operation. It will be obvious that when it is desiredto dump coal'to the right the gate 19 may be similarly operated; givinga clear run of coal from the point x to the point y. Of course bothgates may be operated at the same time and the coal dumped both to theright and to the left It will be observed that owing to the rigidity ofthe toggle-joint systems the gates g and 19 may be slid forwardpositively and will shut oi the flow of coal at any desired time. Thisis quite an important feature of my invention, as it enables me todeliver part of the contents of the truck body at will.

Having described my invention what I claim, and desire to secure byLetters Patent, said bottoms and toggle-joints for positively is slidingthe said gates forward to stop the flow to In a dumping apparatus of thecharacter deof material through the chutes. scribed, the combination ofa truck-body, the 5 chutes B 0 provided with inclined bottoms c PHILIPKRAMER (1 meeting at an apex e, a plurality of gates Witnesses:
